The confession was included in court filings made public yesterday after Rodriguez’s arraignment for murder and assault charges. His wife died after the rampage.

He was ordered held without bail pending his next court hearing.

Rodriguez said in the statement he can’t understand why he attacked Mary Vargas, her mother, Maria Martinez, and Vargas’ daughter, Delia Agosto, but the whole incident started because he was “grouchy” and upset that Vargas, 25, had asked him to get a job.

He said he attacked Vargas first in the bathroom, choking her and forcing her into the bathtub.

When she stopped moving, he went after Martinez, 51, who was lying in a bedroom watching TV. Using an aluminum baseball bat, “I started to hit the mother on the head and the face with the bat.”

Little Delia heard the noise and came in, and “started to cry and scream,” Rodriguez wrote. When he couldn’t calm the little girl down, “I started to choke her, too.”

That’s when he said Delia pleaded for him to stop – and he did, running up to the roof where cops arrested him.
